Abstract: 1407896 Recovering inorganic salts TH GOLDSCHMIDT AG 12 July 1973 [12 July 1972] 33369/73 Heading C1A In a method of rendering reusable and/or disposable a mixture (from liquid salt casehardening baths) of (1) a nitrite/nitrate-containing waste and (2) a cyanide/cyanate-containing waste, which mixture may contain barium, the cyanide/cyanate content of the mixture is oxidized with the nitrite/nitrate content of the mixture, using an excess of the nitrite/nitrate containing portion, by igniting the mixture in the dry state at a temperature above 150‹ C., and after cooling the ignited mixture. In one method the nitrite/nitratecontaining waste is melted at 120‹ to 400‹ C., a proportion of this melt is separated by filtration, and the filtration residue, still having a nitrite/  nitrate content, is used for oxidizing the cyanide/  cyanate content. A reducing agent, e.g. lean coal slack or charcoal, and one or more sulphates of calcium, sodium and iron may be added to the dry mixture to be ignited.

Title: Improvements in or relating to circuit-arrangements for acting upon the natural frequency of oscillatory circuits
IPC: H03C3/20
Filed: 1946-11-11
Abstract: 637,094. Frequency modulation; automatic tuning correction. PHILIPS LAMPS, Ltd. Nov. 11, 1946, No. 33472. Convention date, May 6, 1943. [Class 40 (v)] In an oscillatory circuit 1, 2, with frequency modulated by a parallel variable reactance 3 controlled by a modulating current or voltage (Fig. 2), or variable reactance in series with the oscillatory circuit elements (Fig. 7), an additional reactance 4 is respectively arranged in series or in parallel with the variable reactance so that a linear or other relation is obtained between the modulating current or voltage and the frequency. If the permeability and therefore value of the variable inductance 3 in Fig. 2 is approximately inversely proportional to the premagnetizing current i and the capacity 4 is four times that of condenser 1, it is shown mathematically that the modulation is substantially linear. In place of condenser 4 a negative inductance may be used obtained from across the primary terminals 6, 7, Fig. 5, or Fig. 4 (not shown), of a transformer connected also to the anode and grid of a valve, the grid voltage of which is taken from between a resistance 8 and condenser 9 connected in series across the secondary. Two such valves with grids energized in push-pull (Fig. 5) may be used, a linear modulation being obtained if the negative inductance has a value one quarter that of inductance 2. In Fig. 6 (not shown), a thermionic capacitance controlled by a variable grid input voltage is connected across a parallel tuned circuit 1, 2 and in series with an inductance having a value three quarters that of inductance 2. In Fig. 7, a linear modulation is obtained if the inductance 3 is of value approximately in linear relationship to its magnetizing current i and connected in series with an oscillatory circuit 1, 2 with a condenser 8 of capacity three-quarters that of condenser 1 connected across it. The invention may be applied to frequency modulation or to tuning oscillatory circuits of receivers,

Title: Improvements in or relating to production of niobium pentachloride
Inventor: LIND ROBERT
IPC: C01G33/00
Filed: 1954-11-24
Abstract: Niobium pentachloride low in oxygen is obtained by treating niobium ores or compounds in admixture with carbon with chlorine at a temperature of above 320 DEG  C. and passing the volatile reaction products with excess chlorine into intimate contact with carbon heated to above 400 DEG  C., the carbon preferably being in the form of a porous coherent mass.  Alternatively the carbon may be in the form of particles maintained in the fluidized state by the reaction products and excess chlorine.  The porous carbon mass may be formed from wood charcoal or nut shell charcoal by mixing it with an aqueous solution of an organic binder for example starch, shaping the mixture to the desired form and heating the shaped mass in an inert atmosphere to carbonize the binder.  According to an example a silica tube was provided with a porous plug of carbon prepared by mixing coconut shell carbon with a starch paste and rolling the mixture to produce a cylinder which fitted into the silica tube, the tube then being heated in argon to carbonize the starch.  A mixture of niobite and powdered carbon in excess was inserted in a silica boat into the silica tube and the tube heated to raise the temperature of the silica boat to 400-600 DEG  C. and that of the carbon plug to 500 DEG C.  Chlorine was then passed into the reaction vessel until the reaction was complete.  The niobium pentachloride was condensed and had an oxygen content less than 0.5 per cent.

IPC: D01G19/20
Filed: 1921-12-20
Abstract: 189,363. Nasmith, J. W. Dec. 20, 1921. Combing-machines.-In a Nasmith combing- machine in which the top detaching-roller rolls over the bottom roller as described in Specification 16001/01, the top roller is weighted by a spring, the tension of which is varied to give the greatest pressure when the roller is at the forward end of its movement and the least pressure when it is at the backward end, nearest the nipper. The weight hook H is pivoted on a pin 1 on one end of a lever L rocked by the shaft R, and is provided with a tail T to which is attached the weighting spring 2. The other end of the spring is secured to a lug 3 on a lever K pivoted on the pin 1 and supported by a hook 5 mounted on the frame F. The movements of the lever L cause the points of attachment of the spring to approach and recede from one another, and so alter the tension in the spring. The lever K may be pivoted on an independent pin on the lever L or on the pivot of the lever L, in which latter case the variation in tension in the spring depends solely on the movement of the tail T. The lever K may be lifted out of the notch in the hook 5 by a handle 6 and allowed to fall until a projection 7 abuts against a face 8 on the weight hook and takes the pull of the spring off the roller so that it can be readily removed. The lever K is then supported by the bottom notch in the hook 5.

Abstract: 763,324. Tractor power lift mechanisms. FORD MOTOR CO., Ltd. Nov. 25, 1954 [Nov. 25, 1953], No. 34211/54. Class 79(1). In a tractor hydraulic control system having a single-acting ram and a constantly operating pump the output of which is normally by-passed to a sump, the by-pass is gradually closed to control the acceleration of the ram when a control valve is operated to admit liquid to the ram. A pump 11 draws oil from a sump 9 and normally discharges through a conduit 12, a low-pressure regulating valve 17 and a conduit 16 to the sump. On operating a control valve 20 to uncover a port 22, oil flows through conduits 13, 22a to a shuttle valve chamber 14a. A shuttle valve element 15 is moved to the lift gradually closing a port 15a and thus restricting flow through the conduit 16, and the output pressure of the pump increases. Liquid is supplied to the ram 10 as soon as the pressure is sufficient to overcome a check valve 18. Movement of the control valve to the lift allows oil to drain from the ram through conduits 19, 25, 16 to the sump.
